[drakelist] CW75

2006-04-02 Thread DW Harms








Drakelist de PA2DW,



Hello all,



I am trying to fix a CW75 keyer. The problem is that sometimes,
the dashes will end too early when releasing the dash-paddle. Just as if it was
a straight key.

I am not very good in digital circuits so anybody out
there can help me on the way?

[drakelist] CW-75 problem solved

2006-04-02 Thread DW Harms








Hi all,



I found out that the CW-75 runs much better if I
install the internal 9V battery. So my conclusion is that this keyer is
sensitive to the supply voltage. Though it says to connect a 13,5 V external
line, it seems wise to add some lower voltage, or better regulated?

I thought Id better share this on the list. Anyone
with similar experience? 



I also found the jumper to get rid of the dreaded
dot-memory. What a relief J

[drakelist] Some Drake TR4cw questions..

2006-04-02 Thread Mike Bryce
Hola...

well one can not live by transistors alone. so I dug out one of several old TR4's I had. this one was in fact a TR4CW...

now... I've never used any of my Drake radios for too much, other than to check into a net here or there so there's a lack of operating time on my side.

so here are my questions

1. Using headphones, 8Ω, the volume is way too loud. at just turned on, it's blasts my ears. Is there a fix to this internal to the radio? Or must I insert resistance into the head phone line. ( I don't use the same head phones all the time)

2. Sidetone volume is too low... anyway of increasing the level?

3. When going to the cw filter, I loose RF output power. Yea, could be a misaglined crystal filter, but if I retweak the loading the plate controls, power comes back up to where it was in the wide position.

4. beside ebay at $15 a pop, where can one get the 3/16 inch right angle plugs for the microphone?

thanks... 

mike

Thanks to Garey Barrell who pointed out my error, I am actually looking 
for TWO T4-XB filters, the USB filter and the LSB filter.


Many thanks and 73
